Patent GB-189704950-A (GB)
Title: Improvements in and relating to Knitting Machines of the "Lamb" Class.
Inventor: DUBIED EDOUARD
Filed: 1897-02-24
Granted: 1897-03-27
Abstract: 4950. Dubied, E. Feb. 24. Parallel knitting-machines.-In machines of the "Lamb" class the lowering-cams d, e, f, g, of which d and g are ribbing-cams, are regulated automatically in order to vary the stitch. For this purpose they are held down by springs on stop screws of different lengths carried by revolving turrets D, E, F, G. When a change is to take place a sliding bolt is pushed to the right by contact with a stop raised by a lever operated by a pattern chain, and thereupon, by means of rollers acting on cam levers, presses up the whole of the cams, and then allows them to descend on to the screw stops, which have meanwhile been changed by the pattern mechanism. The changing of the stops is effected by the action of a rack e<4>, pinions and double racks h<4>, h<5> gearing with pinions on the revolving turrets, and the rack e<4> being moved into different positions by the action of sliding bolts c<1> operated by levers from the pattern chain. A special device prevents the lowering of the right-hand cams until the carriage has come to the end of its course to the right, to prevent the tearing of the last tight row of stitching when passing to loose knitting.

Title: Portable Apparatus for Producing Acetylene Gas.
Inventor: DENICH ALBERT
Filed: 1897-08-16
Granted: 1898-07-02
Abstract: 18,907. Denich, A. Aug. 16. Acetylene.-A portable apparatus for carriages, bicycles, and the like consists of two chambers K, L, the former containing the carbide, and the latter containing the water.

The fastening may be released from the inside by a second handle D<1>, the spindle D of which has a crank-pin D<2> which can engage the weighted lever. In the form shown in Fig. 3, a pin a<3> on the spindle B<11> engages with a spirallycut striking-plate C<22>, the surfaces of which serve to tighten or drive open the door when the handle A<10> is suitably turned. The latter is connected by a pin and slot with the spindle B<11>, carried in a bracket B<10> on the door. The pin a<3> may be disengaged from the inside as before by the crank-pin D", or the inside handle D'‹ may be mounted on the door and the two spindles B<11>, D<12> worked in unison by a chain and sprockets. The fastening may be locked by a padlock passing through the eye A<11> and an eyo on the striking-plate. In the form shown in Fig. 1<b>, the weighted lever A<23> impinges on a cam surface B<31> on the striking-plate E<30>, causing the lever to rise and fall into a slot B<33>, from which it may be easily disengaged by means of the knob A<33>.

Granted: 1901-09-28
Abstract: 17,231. Irwin, E. K. Sept. 28. Inhalers.-Relates to an inhaler by which a patient can inhale first air ouly, the exhaled gases escaping into the air, second gas only, the exhaled gases also escaping, third gas only, the exhalations being returned to the gas bag and re-inhaled. It comprises a tube A fitted with a mount C for a face-piece, and a mount F to which is detachablysecured, by a bent rod E adapted to engage under a catch on the part F, a mount D for the gas bag. Mounted to rotate within the tube A is a second tube K, shown in Fig. 4, having an opening M for the inspiratory valve, an opening N having no valve, and a slot R, through which the gases from the outlet valve L, which is placed across the tube as shown, escape. The opening N is normally closed by a shutter G, Fig. 2, which is pressed inwards by a spring B, so that a lug on its under surface engages in a notch on the inner tube, and causes the shutter to be carried round with it. In its first position, the valve M coincides with the opening P in the outer case. On rotating the tube K, the valve M comes opposite the gas mount D, the shutter H being carried forward until it closes the opening P, in which position it is held by a pin Q on the spring B engaging a notch H in the shutter G. On again rotating the tube K, the opening N is connected to the mount D, the slot R is closed by the tube A, and the shutter G remains over the opening P. On reversing the motion of the tube K, the shutter is returned to its original position.
